Gandtee Posted January 5, 2022 Share Posted January 5, 2022 Rhinoceros beetles have destroyed my coconut trees and some palms. They are now attacking my mango trees and boring holes. How do I get rid of them? Chonburi area. Link to comment Share on other sites More sharing options...

drtreelove Posted January 6, 2022 Share Posted January 6, 2022 This is a Dept of Agriculture affiliate program with main office in Chonburi. I have not been in touch for over 3 years and I don't know their current status of services offered, but they did have an active biological control program for pests of coconut palms. Mr. Thiwa, Director Chon Buri Pest Management Center Government office in Pattaya, Thailand Address: 15 Moo 11, Tambon Nong Prue, Amphoe Bang Lamung, Chon Buri, 20150, Thailand Phone: +66 38 231 271 There have been multiple discussions over the years, on this forum and the dog and snake forum, (a.k.a. Plants, Pets & Vets.) Maybe you can search for some of that information. The two big categories of management are chemical control (stem injection with systemic insecticide, spraying with a residual barrier insecticide), which is an option for ornamentals, but problematic with food products due to likelyhood of pesticide contamination. Then there is the "organic", preventive approach, with multiple methods available (sanitation/cleaning up of beetle breeding habitat, trapping of adult beetles, repellents, biological control of larvae and adults, building soil fertility, plant health and natural pest resistance), a couple of which are presented in the Indian video. Practical issues that influence decisions on control methods are size of trees and access to the foliar crown, size of property and number of trees, nature of the property and status of downed wood, debris piles, including neighboring properties/trees and possibility or not for a community cooperative program. Because adult beetles can fly in to your trees from other nearby property, even if you've cleaned up your larvae habitat. Physiologically stressed trees are more susceptible to pest infestation. Dry season drought stress, nutritional deficiencies, methods and materials that are damaging to the beneficial soil biology, like use of high salts NPK chemical fertilizers, herbicides, fungicides and insecticides can be contributing factors. Red palm weevils are often associated in tandem with the CRB infestation, so you have to be aware of their different life cycle and management. Coconut hispine beetle and coconut black headed caterpillar are other common devastating pests to be considered for management. coconut_rhinoceros_beetle__melanesian_057.pdf coconut_red_palm_weevil_180.pdf Link to comment Share on other sites More sharing options...
drtreelove Posted January 6, 2022 Share Posted January 6, 2022 Here's another informational: PowerPoint Presentation (hawaii.edu) Regarding the mango trees, are you sure that its CRB and not a different issue? What signs are you seeing? Photos? Link to comment Share on other sites More sharing options...
